摘要：Medical and aromatic plants in Egypt have been a part of the country's natural and culturaldiversity for thousands of years. Most of the landscape in Egypt is a desert, with a fewscattered oases. Each geographical area has a variety of flora and fauna all adapted to itsown habitat. In recent work we focused on the discovery of this area where these plantsgrow. The plants were investigated in terms of the chemical constituents of the activechemical groups, as well as study the effect of water and alcoholic extracts onmicroorganisms. This work includes five plants collected from the eastern Egyptiandesert areas parallel to the Red Sea coast. These plants are, Acacia etbaica (. Fabaceae),Aerva lanata (. Amaranthaceae), Citrullus colocynthis (.Cucurbitaceae), Ochradenusbaccatus (. Resedaceae.) and Olea europaea, (. Oleaceae). The phytochemicalinvestigation of the alcoholic and water extracts of the aerial parts of the tested plantsshowed the different profile of their contents. A. etbaica, A. lanata, C. coloeynthis, O.baccatus and O.europaea were more or less proportional in their chemical constitution.Flavonoids were common in all of them, and alkaloids dominated them except Acaciaetbaica. Saponins were detected only in Acacia and Aerva lanata. Alcohol and waterextract were tested against four - (G -) bacteria, four (G ) bacteria, one yeast and onefungi. There was a variation in activities; however the water extract of some plants wasthe highest active. It will be better to practice an in vivo experiment to assess the results.
